OUTLET-BOX.

Specification of Letters Patent.

Patented Jan. 1-7, 1911.

Application filed September 15, 1910. Serial No. 582,159.

To all whom it maly concern:

Be it'known that I, FRED I. THAYER, of Farmingtom'in the county ofStraiford and State of New Hampshire, have invented certain new'anduseful Improvements in Outlet-Boxes, of which fication.

, This invention relates to outlet boxes used in electrical.installation in buildings, 'the box being adapted to be incorporated ina wall or partition and to contain anelectric The invention has for itsobject to pro- *vide an outlet box adapted to quickly and with a wallstud and with laths forming conveniently incorporated in a Wall orpartition and to be engaged with the laths and plaster of said partitionwith the minimum expenditure of time and labor.

The invention consists in the improvements which I will now proceed todescribe and claim. Of the accompanying drawings which form a partofthis specification,-'Figure 1 represents a perspective view showing anoutlet box embody ng my invention engaged parts of a partition. Fig. 2'represents a horizontal section .of the same, showing the lath-and-plster portion of the wall or partition comp eted.

Similar reference characters indicate the same-or similar parts in allthe figures.

In carrying out my invention I provide an outlet box made of cast iron.or sheet steel, and having an open front formed by side walls 12, 13andend walls -14, the outer edges of said walls being flush with each otherand forming the margin of the opening into the box. The size-of the box'is.

such thatit is adapted to contain the usual switch employed to connectand disconnect the electric wires -which enter the box through suitableopenings 15- formed in the rear wall or back of the box, said back inthis case having inclined faces 16 in which the openings 15 are formed.

The side 12 of the box is adapted to bear against a wall stud or upright17 forming a support for laths 18 nailed to the outer face of saidstudas usual. The side'12 is provided w th a laterally extending flange19 ada ted to bear on the outer side of the *stud 1 and to receiveattaching screws 20 brother fastening devices which secure the box tothe stud. The inner face of the the following is aspeciflange 19 isseparated from the margin of the front opening of the box by a spacewhich substantially corresponds to the total I thickness of a partitioncomposed of laths 18 and a plaster coating 21 applied thereto,

the arrangement being such that when the box is installed the outer faceof the plaster coating is substantially flush with the face innering'adapted to bearagainst the inner sides of the laths 18 while theinner side of the outer flange 23 is adapted to bear against the outersides of said laths.

In installing the box the side 12 is placed against one side of the stud17 with the flange l9 bearing on the outer 'face' of the stud.Fastenings 20 are then inserted, securing the box to the stud. The laths18 are then nailed to the stud and the laths 18 which otherwise would becontinuous with the laths 18 are inserted at their ends between theflanges 22 and 23, the laths 18 being thus supported against lateraldisplacement by said flanges and held in alinement with the laths 18.'It will be seen,

therefore, that the box adapted as described to be attached at one sideto a stud, and having at the opposite side flanges adapted to engage andlaterally support the ends of laths interrupted by the box, enables theinstallation of the box to be effected very quickly'and conveniently,without the necessityof providing independent supports, such as cleats,for the interrupted laths, these being engaged directly with the flanges22 and 23 of the box.

The box may be r'ovided with a suitable cover or closure a apted toclose the open front of the box, said cover being attached preferably byscrews which enter threaded holes in bosses 24 formed on the ends 1 1 ofthe box, said bosses being formed so that the continuous laths above andbelow the box canpass across them. 1

It will be seen that the operation of at taching the box to the stud 17usually performed by an electrical worker, prepares the way for thelather, whose labor is greatly facilitated by the flanges 22 and 23,these providing all the support that is requisite for theinterruptedlaths 18. k

-5 An outlet box. having an open front and tition, said'flange beingadapted for attachment to.a wall stud, and two lath-engaging flanges onthe opposite side, separated from 15 each other by a space substantiallycorresponding to the thickness of a lath, thetginner flange having itsouter face substantially flush with the inner face ofthe stud-engagingflange, whereby the inner sides of laths,

interrupted by the box, may be supported by 20 said inner .flange inalinement with lath's nailed to the stud, the outer lath-engaging flangesupporting the outer sides of the said interrupted laths. t p

In testimony whereof I have aflixed my 25 signature, in presence of twowitnesses.
